LATERAL-MOTION BEARING FOR JOURNAL BOXES.

Application ined November My inventiony relates generally to inn provements in'lateral motion bearings of the type particularly adapted for use in engine truck driving and trailer boxes and which consists in the combinations` constructions and arrangements herein described and claimed.

An object of the invention is the provision of a railway journal box which has means fory supporting a removable lateral motion bearing of brass or other Vrelatively sott inaterial so that the wheel may turn without any appreciable friction and without excess lateral play, and the bearing can be re- 1'5 placed when worn, quickly and easily and at a relatively slight cost.

A furthervobject of the invention is the provision in a'journalbox ot' the character described ofa removable lateral motion bearing anda novel means for mounting the lateral motion bearing in its associated box so that the bearing can be removed when desired with but relatively little labor andin a relatively shorttime.

A still further object of the invention is the provision in a railway wheel and bearing assembly of means lforsupporting a liner so that the wear'in service will be'greater on the removable bearingiofftheassociated ournalboxthanonany other part oflthebearing structure of the wheel Other objects and advantages ofthe invention will be zapparent'from the Ifollowing description considered in conjunction with the accompanying ydrawingsj in which Figurejl is: a side elevation eti al journal box= iniassociatio'n withA aniaxle and wheel,

In carryingout'-theinvention7 I make use of ajournal boxfhaving a body l' of aconventional*construction The body. 110i' the 'portions 1,V 1926. Serial 110.145,629;

journal box open at both ends as is usual `for the reception of the journal portion-2 'of an associated axle 3, In carrying out the invention.y the body l of the journal box is provided for its open inner end with a sub- .stantially ll-shaped retaining member' 4 whichmay be disposed in inverted position as shown. The :trame'inember 4 overlaps the edge portion of the body l ofthe journal box and is secured rigidlvv to the latter bythe end cap bolts 5 and the side cap bolts 6. It is obvious that the retainin.r member 4 may be formed integrally withthb body l. of the journal box. 'i

v The space-within the retaining member 4 at' the edge of the body of the journal box has a. substantially semiscircular top wall" at 7 and parallel verticall sidewalls at 8.V A retaining groove i s formed in the inner Wall of the retaining member 4 adjacent to the .front edgeof the inner wall of the retaining-'member 4. such groove having a top portion 9 that is formed in the part 7 of the Inner wall of the retaining member and side portions 10 which are formed in the parts Set the inner wall of the retaining'member 4 and which extend-tothe lower endsof the legs'ot the retaining member 4. The retaining groove 10-9-1O preterablyitapers 'in' width 'from its edge towards the bottom as best seen in Figures land 5, being formed with itsy inner side wall disposed at right angles to the longitudinal axis of the body Vo'lthejournal'box and with its outer side wall disposed at an oblique angle withfthe longitudinal axisv ot' the journal box body.

The-legs of theframe member 4 extend below :the level ofthe bottom otthe journal box body and have slots l1 and 12 respectively,- Formed in their extending lower end The slots 11 and l2are in alignment transversely ofthe journal box and are located outwardlyy ot the plane ot the inner side wall of the retaining groove lll-9410. The opening "12 is slightly larger than-the opening' 11 and decreases inV height `from its outer end towards the inner end while the opening 11 `'decreases in height `from vits inner end to itsl outer end.y A tapering supporting key 13 is adapted tobe projected 2, with `the end portions of the supporting key 18 extending laterally of opposite sides loo f through the openings lQand 11 in turn and of the retaining member 4 and in frictional engagen'ient with the walls of the openings 1 11 and 12. one end portion of the key 13 being too large to be projected completely through the opening 12. A cotter pin 14 may be disposed in a transverse opening 15 in the extending` smaller end portion of the key 13 to prevent accidental displacement of the key 13. The key 13 is adapted to underlie an outwardly extending lateral flange 16 on a lateral motion bearing generally indicated at 17 which fits within the retaining frame 4. The lateral motion bearing 17 comprises two (3o-operative sections 17EL and 17b respectively, both of which may be formed of brass or any other relatively soft material. The section 17EL has semi-circular parallel inner and outer walls and the outer edge portion thereof tapers in thickness as indicated at 18 to lit in the portion 10 of the aforesaid retaining groove. The section 17b of the lateral motion bearing has an inner wall which is semi-circular and is complemental to the inner wall of the section 17. The side edge portions of the section 17" taper in width as indicated at 19 to fit in the portions 10 of the aforesaid retaining groove. The laterally turned fla-nge 16 is formed at the lower-'edge of the section 17b of the bearing member and is supported by the key 13. The section 17 L is supported by the section 17b and the lateral motion bearing thus is retained in the frame member 4 so long as the key 13 is in place. rlphe bearing member is adapted to rotatably support the bearing portion of the associated wheel and the wear that takes place because of the rotation of the wheel and the lateral stresses of the wheel will be on the bearing member 17. In order that such wear may be concentrated on the members 17a and 17h, the usual relatively soft bearing liner of the hub of the associated wheel Q0 on the axle 3 is replaced by a hardened steel liner Q1. The bore that is defined by the members 17a and 17 b is sufficiently large to prevent such n'ie1mbers from coming into contact with the ax e.

From the foregoing description of the various parts of the device the operation thereof may be readily understood. The lateral motion bearing can be removed quickly and easily without removal of the journal portion 2 from the body of the journal boX by Vfirst removing the cotter pin 14 and driving the wedge key 13 out of the openings 11 and 12 to permit the lower section 17b to be displaced ina downward direction. A suitable tool then can be placed against one end of the upper section 17a and actuated to swing the upper section 17 a around the journal to a position underneath the journal after which the section 17 a of the bearing can be removed from the space between the legs of t-he lateral motion bearing retaining frame 4. The operation of replacing a new lateral motion bearing 17 and securing it in place in the frame 4, while the journal 2 is in place in the body of the journal box is thought to be obvious.

Obviously the invention is susceptible of embodiments and forms other than that which is illustrated in the accompanying drawings and l therefore consider as mine all such modilications and adaptations thereof as fairly fall within the scope of the appended claims.
